Hi,
I am trying it kick out user once monthly data limited is reached while account-update packet is received. My setup is -
Freeradius ====== internet =========== ISP ===== modem ===== router(running chillispot)
At freeradius i get public IP assigned to modem from ISP and now no matter what IP i try to send COA packet it fails. I have following entry -
Client.confclient 0.0.0.0/0 {        secret      = xxxxx         nastype     = other         coa_server = localhost-coa}
originate-coahome_server localhost-coa { type = coa ipaddr = localhost
 port = 3799 secret = testing1234
# rest all is default......

default (in accounting section)
 update control    {        Tmp-Integer-0 := "%{sql:#query}"        Tmp-Integer-1 := #query}if ("%{control:Tmp-Integer-0}" > "%{control:Tmp-Integer-1}") {
 update disconnect {     User-Name = "%{request:User-Name}"    Acct-Session-Id = "%{Acct-Session-Id}"     NAS-IP-Address = "%{NAS-IP-Address}"}}


Logs shows -

++++[disconnect] returns ok+++- if ("%{control:Tmp-Integer-0}" > "%{control:Tmp-Integer-1}") returns ok++- if ("%{control:Tmp-Integer-1}" != 0) returns ok++[exec] returns noop[attr_filter.accounting_response]       expand: %{User-Name} -> xxxxxxxxxattr_filter: Matched entry DEFAULT at line 12++[attr_filter.accounting_response] returns updatedSending Accounting-Response of id 80 to 12x.162.x94.1x7 port 22626  WARNING: Empty pre-proxy section.  Using default return values.Sending Disconnect-Request of id 188 to 127.0.0.1 port 3799        User-Name = "xxxxxxxxxx"        Acct-Session-Id = "561ad05c00000001"        NAS-IP-Address = 192.168.182.1Finished request 0.Cleaning up request 0 ID 80 with timestamp +26Going to the next requestWaking up in 2.0 seconds.Sending Disconnect-Request of id 188 to 127.0.0.1 port 3799        User-Name = "xxxxxxx"        Acct-Session-Id = "561ad05c00000001"        NAS-IP-Address = 192.168.182.1Waking up in 4.3 seconds.Sending Disconnect-Request of id 188 to 127.0.0.1 port 3799        User-Name = "xxxxxxx"        Acct-Session-Id = "561ad05c00000001"        NAS-IP-Address = 192.168.182.1Waking up in 8.6 seconds.Sending Disconnect-Request of id 188 to 127.0.0.1 port 3799        User-Name = "xxxxxx"        Acct-Session-Id = "561ad05c00000001"        NAS-IP-Address = 192.168.182.1Waking up in 14.9 seconds.No response to CoA request sent to 127.0.0.1  Found Post-Proxy-Type  WARNING: Unknown value specified for Post-Proxy-Type.  Cannot perform requested action.# Executing group from file /etc/freeradius/sites-enabled/defaultFinished request 0.

Can someone please guide me if i am missing some conf. somewhere or it is not possible considering my network topology above. Also, i have set coaport 3799  and coanoipcheck  in chilli.
